Norwegian authorities reported that a radioactive leak had taken place at a nuclear research reactor in southern Norway. The reactor at the Institute for Energy Technology (IFE) in Halden leaked radioactive iodine, the Norwegian Radiation Protection Authority (NRPA) said. Those working at the reactor at the time of the discharge on Monday were evacuated from the facility.

Officials say the leak has now been contained according to the IFE.

In a statement, the NRPA said the fault occurred “due to a technical failure during treatment of the fuel in the reactor hall”. The incident is not expected to harm the environment outside the reactor, it added.
